The Stanford researchers took 100 students through a series of tests. Half of the group claimed to be masters of the multitask. The other half worked a step at a time.

In one test, the groups were shown two sets of different colored triangles and told to ignore a certain color and count the other. The step at a time group had no problem counting, while the multitaskers were constantly distracted by the second color triangles and basically failed the assignment. Remember, these are Stanford students who are supposed to have a high level of intelligence.

Multitaskers also failed in tests of memory.

And that is not all. They also failed at the thing they are supposed to do best, which is switching from one thing to the other.

Researcher Eyal Ophi said multitaskers couldn't help thinking about the task they weren't doing. "The high multitaskers are always drawing from all the information in front of them. They can't keep things separate in their minds," Ophi said.
